Farmer management of plant germplasm pre-dates crop domestication, but humans' role in crop evolution and diversity remains largely undocumented and often contested. Seemingly inexplicable practices observed throughout agricultural history, such as exchanging or replacing seed, continue to structure crop populations across the developing world. Seed management practices can be construed as even...

maize genotypes were screened for host resistance and seed treatment chemicals were evaluated in field to manage fusarium ear rot complex of maize at high- and mid-hill environments in nepal during 2003 and 2004. seven popular maize genotypes along with a susceptible check were used in the host resistance study. the maize genotypes adopted from exotic sources, manakamana-3 and deuti, performed ...

Seed purity, more appropriately seed product integrity, is maintained within a framework of regulatory (labeling) requirements through the Federal Seed Act, quality standards, seed testing performed by accredited entities, quality management practices, and production under principles and practices of coexistence. Cooperation among seed developers, seed producers, and growers at the local field ...

BACKGROUND Management regimes for vegetation restoration of degraded grasslands can significantly affect the process of ecological succession. However, few studies have focused on variation in the soil seed bank during vegetation restoration under different management regimes, especially in saline-alkaline grassland habitats. Our aim was to provide insights into the ecological effects of grassl...

A study was conducted for assessing quality of 15 hybrid rice seed samples and management of seed borne fungal pathogens by three selected chemicals namely Bavistin (0.3%), Thiovit (0.3%) and Provax (0.3%) along with two botanicals such as: Garlic extract (Allium sativum) (1:1) and Allamanda leaf extract (Allamanda cathartica) (1:1) and a bio-control agent BAU-Biofungicide @ 3% (Trichoderma bas...
